i gen with libraries locally. are you wanting the types that look like pictures or just basic qr?

If it’s just text based stuff I sometimes use -

or a more complex toolkit -

Automatic111 I think has a QR Generator plugin if you wanted image manipulation.

I use the command-line utility qrencode, it's available in most package managers.

If it is just for one-off stuff these days most browsers let you share links in QR code format, when you pull up the qrcode you can modify the text box as you see fit

If looking to customize qr codes, toss in "styled qr code" into GitHub and I'm sure a few WebApps will pop up
